Fixing 0 IMEI

Hello. I've been getting a lot of emails on how to do that and i thought i should make a thread here.
Now you got to have the original box in which there is the imei written. I don't take any credit for this guide as i didn't write it but i found it somewhere here but it doesn't exist anymore. I'm not responsible for any damage may happen to your phone. I did it several times after flashing official 2.3.5.
It has worked fine with my IDEOS X5 U8800.
1. Tools
a. Drivers for U800 32bit win 7 (tested and work )
http://www.2shared.com/file/fnP5fc8G/u8800Drivers.html
b. Drivers for Android 32 and 64 bit win 7 (not tested )
http://www.2shared.com/file/ZNZ4Q0lk...012_09_12.html
c. Software for restore
http://www.2shared.com/file/xBxUOnPz/DFS.html
2. Enable debugging by USB in the settings.
In call type * # * # 2846579 # * # * http://postimage.org/image/tnj4s2dyj/
3. Go to ProjectMenu -> Background settings -> Usb port settings put the Manufacture mode and corfim.
4. Go again to ProjectMenu -> Background settings -> Qualcomm backround open settings put the background open. Password 0 and corfim.
5. Go again to ProjectMenu -> Background settings -> Log setting -> Log switch put log on and corfim.
6. Now conect your phone to pc and install the drivers.
You must see this at your device manager http://postimage.org/image/5lrm61agd/
7. Instal DFS and run.
8. Click Ports, select the port with the signature DBAdapter Reserved Interface (double click) to close.

10) Press the SPC, the bottom will Device Unlocked.
11) Select Programming and in the IMEI write yours and press Write.

13) Check Imei, may appear after a reboot, if not try a few more times to try to set the port speed to 115200 (box to the left of DM)
Check IMEI *#06#
As soon as the IMEI restored change:
* # * # 2846579 # * # * -> ProjectMenu -> Background settings -> Usb port settings to put on the Manufacture mode google mode (or normal if you do not get up google)
* # * # 2846579 # * # * -> ProjectMenu - > Background settings -> Qualcomm backround open settings put close
Good luck..

Thanks a lot... now I got my imei back. But now I have one another problem, I installed ics rom and now my wifi Mac id is 00:00:00:00:00:00. Are they related?

This procedure did not work for me. I found it a couple of weeks ago in another thread (http://forum.xda-developers.com/showthread.php?t=1591997) and gave it a try (numerous times) without success. I was able to complete all steps up until actually writing the new IMEI. I attempted to write it a couple of dozen times without any success. It appears to work but the lMEI never actually changes.
I also found another procedure using a program called NVedit but it would give me an error stating the NV location was set to read only (I forget the actually wording). It seems that my phone has the location that contains my IMEI locked in some way that nothing can change it. So I gave up on that phone and am using a different one that I bought on eBay, brand new at a dirt cheap price ($27.00).

are you rooted? i remember having these issues when i flashed 2.3 after 4.2 rom. u first need ti flash 2.2 then 2.3 and that should work

Yes, I am rooted.
I started out on 2.2 way back in the beginning. Then I flashed 2.3.5. That's when I lost my IMEI and replaced the phone.
But I wanted to keep experimenting at getting it working 100% even though I had a new working, rooted, and customized phone. Using 5IromToolBox I restored a backup from the new phone to the broken phone just to see if it would work. Then I flashed Stallion-51-ICS custom ROM. It is a GB based ROM with look and feel of ICS.
When I run the procedure in this thread, everything looks as though it has worked, but the IMEI never changes. So what did 5Irom do differently that it was able to restore the backup from a different phone but I cannot use DFS or NVEditor to write to the locations? The back I made from the new phone and restored to the old one is Consumer Cellular so I suspect they have locked something out that 5Irom is able to get around but other tools don't.
On another note, just for the heck of it I tried to upgrade to ICS from GB and it fails on the first update step. Go figure.
If I could find a full-flash procedure for the pro and 51 versions of this phone I suspect I could resolve all issues. Who knows?
UPDATE: I went through the whole process again and noted a point I forgot to mention. In DFS at the bottom of the screen EQF is yellow, not green. I don't recall exactly what that means but in reading through the DFS doc, it states that writing a new IMEI is not possible as long as EQF is yellow. When I enter my IMEI and click on the WRITE command the response is "MODECHANGE OfflineD OK"

it should be green! what i would do is to flash 2.2 then 2.3.5 and follow again the steps very carefully! maybe u ever flashed a partition and it's not the default one? i can't really help you :/ try this and if it doesn't work make a thread in the q&a section

Yeah, I knew that it should be green. The bottom line is I do not have the 2.2 image to flash. I would have done that a long time ago if I had it. All I have is the DiskImage backup that I made off of my new phone. When I flashed it onto the old phone it starts, displays the Consumer Cellular logo for about ten seconds then shuts off immediately. As far as starting a thread in Q & A, I did that weeks ago and got nowhere fast.
Any link I have found for the original 2.2 for -51 and pro is usually a broken link. or it takes me to download that stupid iLivid program that doesn't do squat to get the files I need. I did find a DiskImage file that somebody made and posted but it is almost 4 gig in size. You are supposed to use Pink Screen to load it but Pink Screen only gives me access to the image directory and it's only 256 meg.
Thank you for your time and suggestions.

I believe in the wiki section there are links to default 2.2 and 2.3.5. The ones I found a long time ago were from Blefish, although I'm not sure. Good luck!

Dead link.
Hi.
I try to download the "Drivers for Android 32 and 64 bit win 7 (not tested )", but its a dead link. I run win7 pro, and somehow the 32 bit driver doesn't work.
Would like to try the 64 bit driver. Could u reupload it, please?

I just did a repost cause i veen asked a lot of times I don't have the files and I don't thinks drivers are needed. You could just install huawei's suite for PC

Hi All,
Many thanks for this post.
Iv recently installed the Blefish CM11 rom for U8800 and its works fine. Only issue I have is IMEI=0. I can make and receive calls and even use the mobile internet.
My question is - Is there a way to edit the IMEI no on KK4.4.2 ROM through entering in the engineering mode?
or else, will have to start from the beginning (stock rom process as mentioned in the OP).
thanks for your help.

Hi,
I haven't found out the way to fix it yet.
Only way I got to fix is to redo the stock rom, root, save the imei and the reflash the custom rom.
The reason for the imei issue was changing the partitions
thnx anyways

this guide that you have post it has been made by me and at least you should have say that is ported from me. Even the links that you have are in my acount. YOU ONLY COPY MY POST . you could ask me to repost it or just mention me. Check this link http://forum.xda-developers.com/showthread.php?t=1876501

[help] I see my IMEI but...

Hi all, i've purchased an SM-G900F but there is a problem, it has rooted.
I've noticed those :
- I can see IMEI number (if i do #*06#) but my EFS folder is empty
- When turn on WiFi , the device will reboot automatically and appear " Factory Mode is On"
- i can make first call with sim , after i'm unable to call , but the 3G network works
- Whit ES File Explorer i've see that my efs folder is empty (But i can see my IMEI with secret code)
- In Device Info i see one time "Official Status" and another time "Personalized Status"
I'm tinking that old owner is a very st......d guy. Howewer these are all information :
Model : SM-G900F
Version : 4.4.2
BASEBAND : NE2
BUILD : NE2
What do you think? How i can solve the problems?
EDIT 1 : i've formatted from recovery , now it ask me to insert the samsung account of old owner...

- Use Phone INFO ★Samsung★ app to obtain more detailed information about your device, including Model, Baseband, Bootloader, CSC, IMEI, S/N, etc...
- May be the Reactivation lock has been enabled. You should ask the ex-owner for the account.

reactivation lock is on. you will need to contact old owner. There is also a way to "fix" that but not sure if it is appropriate for XDA.

The guy was not traceable now. He's vanished ....

You are kinda between a rock and a hard place if reactivation lock is enabled and you don't have the login to toggle that. In most cases that means that the phone is stolen and this is an explicit anti theft feature. You need that login from the original owner. Or if you have the original receipt, you might be able to convince a Samsung repair center to disable the reactivation lock for you.
In any event, as to your original question the most likely cause of the problem is a corrupt configuration file, namely a text file named "factorymode". You can try this repair from the command line or a root aware text editor.
Code:
echo -n ON > /efs/FactoryApp/factorymode

Great. But you neglected to tell us if you tried (or even noticed) the suggestion to check your factory mode configuration file. The contents should show "ON" (yes, "ON") and the permissions 0644. Your efs folder may appear empty to you when it really isn't. It depends on whether you have your file browser (or command line options) set to display hidden and system files or not.

y factory mode is on , because i can't acces my wifi, and it appear that factory mode is on. I've set to see hidden files , but now i haven't root on my device
Edit: terminal emulator say : no such file or directory
Edit 2 : Solved with terminal emulator and busy box Thanks to @leoaudio13 for his dump
These are the command for mount efs :
su
mke2fs /dev/block/mmcblk0p12
mount -w -t ext4 /dev/block/mmcblk0p12
reboot
After then , with text editor i've disabled FactoryApp in efs folder tanks to all

.
For the benefit of anyone else reading this thread, do not repeat the steps in the post above until
you understand what they do. A typo in those steps could easily cause you endless grief.
Glad you go it working.
If those steps fixed your issue, then you mislead us with erroneous information earlier. You said that you had an empty efs folder earlier. But those steps would not have been necessary or effective if that was accurate. You must have had a missing efs partition. There is a considerable difference between an empty and nonexistent item and that datum would have led us to a solution.
On a normal phone, there would be an extant efs folder and it would be automatically mounted at boot. A missing folder strongly suggests that the wrong firmware or a flash error took place. Presumably by the previous owner.
Anyone using the make filesystem command mke2fs /dev/block/mmcblk0p12 should be very careful with typos as an incorrect address could cause major corruption that would be difficult to recover from.

could be a block imei by the operator? if it is POSSIBLE to solve? or it could be due however to the efs folder, or the firmware, modem?

As you can read i said, Ive got almost the same problem, i don't say we have the same problem. in a sense that previous owner account or the reactivation lock is present. sorry if i made a statement that bothers you, just looking for a solution.

hello guys, always about the efs folder I was reading this post: http://forum.xda-developers.com/showthread.php?t=2705524.
according to you through this tool is possiblile restore the backup I had done with samsung tool? I would like to try this because the efs folder on my sm-g900f is 23kb, but the backup I had done with samsung tool is 14mb !! what do you think?

Once it comes back on, it might take a minute or two for it to acquire signal so don't panic.
DO this on your own risk.. No body is responcible for any lost
Conclusion:
The only real way to know if the whole thing got applied is to do steps 1 through 10 again (obviously skipping installations)
and reading all values or if you are in an area where you previously had bad or no reception.
You can see unlocked GSM/UMPTS bands from the *#*#4636#*#* /Phone information /Menu /Select radio band

Don't forget to put check marks on dual sims, and apply all settings to sim0 and sim1 (see attachment). By the way before u messed things up, back up your modemst1, modemst2, fsc, and fsg.
By the way we can also use qxdm to recover lost imei, just go to 0550, and insert your imei for SIM 1 (sim0 in qxdm) and SIM 2 (sim1 in qxdm), for example:
Code:
If your IMEI was: 954091051099226, then the boxes would look like so:
8
9a
45
90
1
15
90
29
62
or also recover lost esn (item no 0 and 5597) or meid (1943 and 5598).

Great guide, guys !:good::good::good:

Need help for prevent NV recovery from you all

If it's the same as the 1+1, replacing /system/bin/rmt_storage with a version not locked would prevent nv recovery (do you know if NV values were sticking in an older version? If so, take it's rmt_storage and try to replace current one with older one, I think it's worth trying)

Hmmm, as far as I know, all NV settings, including IMEI, or MEID, ESN, etc, resides in your modemst1 and modemst2 partition. If you don't believe me and eager to try, first make a backup of those two partitions, then format or wipe the two partition inside your phone (use fastboot to do this), I'll bet for your YU, now your IMEI and NV settings are all gone.
To be honest, I just found out from this thread that there is an rmt_storage in CM phones, wkwkwkwkw, . If the rmt_storage function is trough, then CM is locking the phone NV settings from the HLOS side not Non-HLOS side. I'll do some research on this rmt_storage.

Need Help from your side

Hi there, attached is boot.img and a hack rmt_storage for CM 12.1. Just flash the boot.img to your phone and connect it with QXDM. Your phone will be recognized as qualcomm diagnostic port 903A. Copy and paste (you can use TWRP's file manager to do this) the rmt_storage to "/system/bin" and change its permission (chmod) to 0755. This will make your changes stick upon reboot.
By the way, to use all these files, you need to be on stock CM 12.1. I haven't tried it on any other ROM.

I have tried doing this on Yureka - CM11 XNPH05Q. Installed all the drivers & softwares successfully. When I startup the QPST config to add a new port,
1. I have to uncheck the "Show serial and USB/QC diag ports only" to make the HTCUSBModem port visible.
2. Although I am able to add the port successfully I am unable to see the phone number, it says "No Phone".
Since it is unable to get the phone details I am unable to proceed further. Nothing is visible/editable QXDM. either.
I have manually edited the build.prop file to make sure USB debugging is enabled but to no avail. Please check the attached files, what is it that I am missing?
P.S - I am able to get my IMEI number using *#06#

Any suggestion Guys???

[REQUEST] EFS Backup with IMEI zero IMG/TWRP

People, i'm going crazy with this...
In these last days i've been trying to make my Gionee work but with no results...
All works GPS, WIFI, FM Radio and even NFC... all but what is most important in a phone, the ability to make and receive calls/sms etc... No signal...
At this time i believe its the modemst1 that is damage some how... the modemst2 is ok and it has the IMEI...
Both of this files are at /dev/block/platform/msm_sdcc.1/by-name/, and by what i can tell their both 1.5Mb...
It seems that modemst1 might contain other relevant information for the process of registering on the network...
What i ask now doesn't requires an expert knowledge of Android.
I believe that any Android user should know this operations, for his own safe guard!
During the process THE SIM CARD MUST BE OFF THE PHONE
Changing IMEIs
This process can be skiped if you trust me and believe when i say that i dont wont your IMEI.
Just want my new phone to work again... As soon has i got your backup and restore it, i'll change the IMEI to my own...
Requirements:
EFS_Professional_2.1.80_BETA - Download HERE
This tool can be used to change the IMEI. Change it 00000(...) before start the backup and after completed change it back to your IMEI.
During the process THE SIM CARD MUST BE OFF THE PHONE
1 - Open application and choose "Qualcomm NV Tools" press ok to confirm
2 - Select the Diagnostics Port and press connect
3 - Go to "Secure Ops" and press SEND the Diag password
4 - Check the IMEI (Dec) box and change the IMEI
5 - Below the IMEI (Flipped) area make sure its selected Phone and press Write
6 - Disconnect and reboot the phone. Confirm if your IMEI has changed before starting the backup process
Process 1 - Backup to IMG files
Requirements:
- ADB available on your PC or Terminal Emulator app installed in your phone
- Phone rooted and BusyBox installed [get BusyBox from PlayStore its free]
Using the Terminal Emulator or ADB in command line, type these commands:
Code:
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/storage/sdcard0/efs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/storage/sdcard0/efs2.img
Process 2 - Backup with TWRP Recovery
Requirements:
- TWRP Recovery installed - Download version 2.8.6.0 HERE
1 - Reboot into Recovery Mode
2 - Press Backup
3 - Select only the EFS partition
4 - Rename the backup (optional) and press Backup
In both processes you can choose just to share with me only the modemst1 backup.
I believe that the IMEI information is on the modemst2.
The backup procedures dont have any risk to your phone.
Changing the IMEI carrys some risks... If you're not sure of this, just DON'T DO IT.
Or simply trust in me, and backup without changing your IMEI
Again, people i just can't put in words the suffering that i've been in this last 2 weeks...
Please anyone, just end my personal hell...
Thanks you all

please someone share you efs backup from e7 32GB indian version..

Should I use this fix only on Android 4.1 and 4.3?
Do not try this on Archidroid 3.1.5 (Android 5.1.1)??
EDIT:
8. Choose GT-i9300 on the List & COM Port

It says "Card not found" (running OctoplusSamsung.exe), but application is running
I choose GT-I9300, COM port only COM5 available, I press Read Info button, and there is "Reading info, please wait..." and nothing happens
When I try to start Loader Octoplus Samsung.exe - nothing happens.
According to Windows Defender, unins000.exe has Virus/Win32/Sality.AT

After Flashing the EFS file you provided, I've lost my IMEI as well.
Of course the repair network option completed successfully. But it didn't fix the no network problem. It just created one more problem and my IMEI is now generic.

Please turn off your virus gurd first
